Application filed December 26, 1917. Serial No. 208,745.

T 0 all whom it may concern:

Be it known that I, HENRY W. ODowo, a citizen of the United States, and a resident of Jersey City, county of Hudson and State of New Jersey, have made certain new and useful Improvements in Gas Stoves, of which the following is a specification.

The invention relates to gas stoves, and more particularly to ,means for controlling the supply of. gas to the burners of a gas stove and for indicating the operation of said means. V

Objects of the invention are to provide an improved form of gas stove which shall be proof against leakage of gas; whose gas supply means may be operated with safety, certainty and convenience; which shall be capable of indicating the operation of sald gas supply means; and which shall be simple and durable in construction and economical, efficient and certain in operation. These and other objects of the invention will in part be obvious and in part be more fully explained in the following description.

The invention consists in the novel parts, improvements, combinations and features of construction herein shown and described.

r In the accompanying drawings, which are referred to herein and form part hereof, is illustrated an embodiment of the invention, the same serving inconnection with the description herein to explain the principles of the invention.

Of the drawings:

Fig. 4 is a perspective viewof means for operating the valve;

Fig. 5 is a front elevation of the dial and pointer which indicate the position of the valve; and 1 a Fig. 6 is a section taken on the line 6-6 of Fig. 5.

A gas stove constructed in accordance with one feature of the invention includes, in combination, a main gas supply pipe, a plurality of branch gas supply pipes, and means for controlling the supply of gas to said branch pipes, whereby gas will be supplied to one only of said branch pipes at a time.

In one embodiment of this feature of the invention, the main gas supply pipe has a pair of branch supply pipes communicating therewith, and a valve is arranged between said main and branch pipes, said valve hav ing ports arranged to communicate between said main pipe and one only of said branch pipes at a time.

According to another feature of the invention, means are provided for operating the valve and for indicating its position with relation to the supply pipes, whether closed or open, and if open, to which branch plpe the gas is being supplied. In one embodiment of this feature of the invention, a dial is provided which has ,marked thereon the various positions of the valve with relation to the branch supply pipes and the burners fed thereby, and a pointer for indicating said positions is provided, there being also provided 'connecting'mcaus, as a ro between the'pointer and the valve, the connection of said rod with the pointer and valve being so arranged that by moving the pointer to any desired position on the dial, the rod will be caused to actuate the valve to move to the position so indicated.

These and other features of the invention will be more fully set forth in the following description and in the drawings.

Referring now in detail to the drawings, there is illustrated therei as a preferred embodiment of the invention, a stove which has the usual top 7, to the burners of which gas is supplied by a main gas supply pipe 8 and connecting pipes. the supply of gas through which is controlled by the valves 9 and 11.. There are also provided a broiler 12, suitably arranged in the compartment 13, and having the usual Bunsen tube 14- and an oven 16 heated by a burner 17 conveniently arranged in said oven and having the usual Bunsen tube 18.

Gas is supplied to the broiler burner 12 and oven burner 17 through the main gas supply pipe 8 which communicates with the branch supply pipes 21 and which in turn communicate, respectively, with the broiler burner 12 and the oven burner 17. ln gas stoves of this type in which the supply of as the burners of the broiler and.

which arranged to communicate with the main gas supply pipe 8 and also with the branch gas supply pipes 21. and 22. Said valve i comprises an outer casing 2aand an inner rotating member 25 which is formed with a diametral port 26, which port, in the position of the parts shown in Fig. 2, at one end 2'? communicates. with the branch pipe 21 leading to the broiler burner 12, and at its other end 28 communicates with the branch supply pipe 22 leading to the oven burner 17. The valve inner member 25 is formed also with another port 29 at right angles to the port 26 and adapted, when in certain positions to which further reference will be made, to communicate with a port 30 formed in the outer casing 24; of the valve and through this latter port 30 to communicate with the main supply pipe 8.

It will be noted that when the valve 23 is arranged in the said position shown in Fig. 2, its diametral port 26 will be in open position toward orcommunicating with both the branch pipes 21 and 22, but the port 29 will be in closed position, that is, not communicating with any of the pipes 8, 21 or 22, and hence the gas will not be supplied to either said broiler burner 12 or said oven burner 17. This may be termed the normal closed position of the valve. In order to supply gas to the broiler burner 12, for instance, the valve member 25 should be rotated through a quarter revolution in the direction to bring the end 27 of the diametral port 26 into communication with the port 330 and the supply pipe 8 and to bring the port 29 into communication with the branch supply pipe 21, while the port 26 will be closed at its end 28 by the inner wall of the outer casing 24. Conversely, if it is desired to supply gas to the oven burner 17 the valve member 25 should be turned in the direction opposite to that just described and in the direction to bring the end 28 of the port 26 into communication withthe port 30 and the pipe 8, and to bring the port 29 into communication with the branch supply pipe 22 leading to the oven burner 17'.

It will be noted further that if, for exam lass Preferably and .as shown, said means comprise a valve 23 ple, the rotation of the valve member 2 3 from its closed position to its open position with relation to the broiler, as described, could be continued further through, say, an other quarter revolution, the port 29 then would be in communication with the port 30 and pipe 8, and the diametral port 26 would be in communication with the pipes 21 and 22, this arrangement of the valve and the supply pipes permitting the supply of gas to the broiler and oven simultaneously. In like manner, a similar continuation ot' the rotation of the valve member 25 from its closed position to open position with re lat'ion to the oven supply pipe, as described, would bring about communication between the port 29 and the port 30 and pipe 8 and betweenthe diametral port 26 and the said supply pipes 21 and 22, and thus permit the supply of gas to both. broiler and oven at one time. V

Means are provided, therefore, forlimiting the movement of the rotating member of the valve and preventing the possibil: ity of the effecting of any arrangement Oil the valve 23 and the supply pipes 8, 21 and 2 2, which would permit communication be tween the said pipe 8 and the said pipes 2i. and 22. simultaneously, as described. Preterably and as shown, see Fig. 3, the outer casing 24; of the valve constructed with a portion 31 projecting at one side somewhat beyond the other portion 32 on the other side, and forming on opposite edges stops 34 and 36 with each of which a pin 37 rigidly attached to the exposed portion 38 of the inner valve member 25 contacts, when the said inner member 25 is rotated in a proper direct on a quarter revolution from its normal closed position, as shown in Fig. 2. It will be seen that the construction and relative arrangement of the valve parts and ports, the in 34 and the pipes 8, 21 and 22, are such that when the inner valve member 25 is rotated through the said quarter rev-- 1 .0 olution in either direction from its normal closed position, the ports and pipe which should then be in communication, as above explained, will be in exact registry for full and proper communication.

i Additional means for limiting the movement of the valve member 25 to a half revolution or quarter revolution in either direc-. tion from its normal closed position, are provided in connection with. another feature of the invention, the indicator, which will presently be described.

It will be observed, furthermore, that in the construction described, the valve mem. ber 25 can be turned from its open position with relation: to the broiler supply pipe 21 to the open position with relation to the oven supplypipe .22, or vice versa, only by passing through the closed zone, that'isto say, only by turning the valvemember 25 first to closed position and then to the open position desired. This not only prevents the supply of gas to the broiler and oven simultaneously but affords the further advantage that leakage of gas is avoided while passing from one open position of the valve to another.

Means are provided for operating the valve, which means comprise, as shown, a wing 39', preferably rigidly attached to or forming an extension of the valve member 25 and by means of which, as will be apparent, said valve member will be actuated. As the gas supply pipes and the valve 23 may not'in all cases be easy of access, means are also provided, see Fig. 4, by which the valve maybe operated from a more convenient position, say, in front of the stove. Said means comprise a bar 41 of suitable length to reach from thevalv'e 23 to the front of the stove. While the bar 41 maybe fastenedto the valve 23 in any suitable mannen'it is desirable, for reasons pertaining; to the indicating feature of the invention presently to bedescribed, that the bar 41 be yieldingly connected to the valve, and, therefore, preferably-and asshown, the inner end of the bar is bifurcated or forked to engage, between theresulting tines 42, the wing 39; Through orifices 43 in the tines 42 of the bar 41 and through an orifice 44 in the wing 39 extends 'apin 45 which'thus serves to hold the bar and wing insecure engagement. To permit the engagement to be -yielding,'however, the orifice 44 is mac e somewhat larger than the respective orifices 43, which permits a reciprocatory movement of the bar 41 in the direction'of its length, the purpose of which will presently be explained. The pin may be of any desired form or construction, as shown, a cotter pin made of spring metal being employed. The bar 41 terminates in a member 46 by means of which the bar mav be operated to actuate the valve member 25. The member 46 also serves another purpose, to which further reference will be made.

According to another feature of the invention, means are provided for always indicating the position of the valve, whether in its normal closed position or in open position with relation to the broiler or the oven.

In the embodiment of the invention illus-' of the valve 23. At the proper places on the dial, see Fig. 5, will be marked the points to which the pointer 46 must be .are formed on the dial 7 turned in order to put the valve in the cor responding respective positions. By turning the pointer to the point marked Broiler. for example. the valve member 25 will be turned to its open position with relation to the broiler burne and thus will be supplied to said burner. Similarly, if the pointer l6 be turned to the point marked Oven the valve member 25 will be turned to the position proper for supplying gas to the oven burner; In like manner, if the pointer 46 be placed at the point marked Gas off, the valve member 25 will be positioned in its normal closed pbsition, that is, cutting off the supply of gas to the stove. As heretofore explained, the rotating valvemember 25 can only be turned from its open position with relation to the broiler burner to its open position with relation to the oven burner, or vice versa, by turning said member 25 the direction in which the valve should be arranged in order to cut oil the supply of gas. Thus, to move the pointer 46 and so actuate the valve member 25 from broiler to oven or the reverse, the pointer must be moved in the direction to pass the point marke l Gas off.

As hasheretofore been alluded to, additionalmeans are provided'in connection with. the indicatingineans'for limiting the move ment of the valve, said additional means, preferably and shown, consisting of bosses 49 and 51formed and suitably disposed on the face of the dial 47, see Fig. '5, so that the pointer 46 will, preferably through its shoulder 52. presently to be described, co ntact with the appropriate boss when the pointer 46 has. reached the open position with relation to the broiler or oven burner, and further movement in that direction will thus be prevented.

Means are provided for locking the pointer 46 and the rotating member 25 of the valve 23 in any position to which they are moved and thus further safeguarding the operation of the stove. In the embodiment of the invention. illustrated recesses 53, 54 and 55 in the vicinity of and communicating with the orifice 48, and the shoulder 52 is formed at the base of the pointer 46 and is adapted to fit snugly between the side walls of the respective recesses 53, 54 and 55. The said shoulder 52 is preferably so located that, when the pointer 46 is in position indicating; Gas oil, the shoulder may be placed in the recess 54. As shown, the other recesses 53 and 55 are located each at a distance from the recess 54 equal to a quarter revolution of the pointer 46, so that when the pointer indicates the position oven the shoulder 52 will rest in the recess 55, and when the pointer indicates the position broiler the shoulder 52 will be positioned in the recess 53. It will be seen that when the shoulder 52 is thus placed. in one of the recesses 53,

or 55,.the pointer 18 secured against further rotation in any direction. In order,

however, to hold the shoulder 52 in the recess in which. it may be placed and thus prevent accidental movement of the pointer l6 and the valve member 25, means are provided for locking the said. shoulder 52 in the said recess. In the preferred embodiment of the invention illustrated in the drawings said locking means comprise a spring me nbcr 57, made of suitable metal, which fastened in any desired way to the reverse side of the dial 4:7. This-spring member is bifurcated at its lower portion loosely to engage the bar 41 upon which is formed a stop member 58 against which the lower end of the spring 57 abuts, all as clearly shown in Fig. 4. It will be observed that any withdrawal movement of the shoulder 52 from any of the recesses 53, 54 or 55 in which it may be placed preparatory to moving the pointer 46 must be made against the action of the spring member 57, which memher is .made of a suitable strength to insure the secure locking of the shoulder 52 in any of the said three recesses and yet not to interfere with the proper manipulation of the pointer. To unlock the valve for operation, it is merely necessary to pull outwardly on handle 46 against the tension of spring 57, whereupon the valve may be turned.

It will be seen that a gas stove constructed in accordance with the invention as heretofore described will carry out the objects of the invention as enumerated and will possess in addition other advantages which will be apparent to those skilled in the.

In its broader aspects the invention is not limited to the precise construction shown and described nor to any particular con.- struction by which the invention has been or may be carried into effect, as many changes may be made in the details thereof without. departing from the main principles. of the invention or sacrificing its chief advantages.
